WebQuestion: 1. During a relative refractory period of an action potential A. The presynaptic neuron "tells" the postsynaptic neuron about the "relative" strength of signal B. Another action potential can be fired, but it takes a greater stimulus for the membrane potential to reach threshold C. Ca++ flows out of the cell, causing hyperpolarization ... WebOnce the sodium channels open, the neuron completely depolarizes to a membrane potential of about +40 mV. Action potentials are considered an “all-or nothing” event, in that, once the threshold potential is reached, the neuron always completely depolarizes.

WebTo reduce the risk of cross-contamination during the sampling event, all sampling equipment was decontaminated with 20% (v/v) sodium hypochlorite solution (household bleach) and then rinsed with Milli-Q water onboard before and after fieldwork. Sterile nitrile gloves were used when in contact with water samples. WebA voltage change that reaches threshold will cause voltage-gated sodium channels to open in the axonal membrane. The influx of sodium causes the rising phase of the action potential, but the ion flow also depolarizes nearby axon regions. As the depolarization reaches threshold, the action potential moves down the axon.
